Embodiment Construction

[0021] As shown in the accompanying drawings, the large-length, large-section high-voltage optoelectronic composite submarine cable three-dimensional twisting machine of the present invention includes a tray drive motor 2, a mechanical slewing bearing 3, a frequency conversion motor 4, an electrical slewing bearing 5, and a conductive device 6 , stranded body PLC system 7 or main PLC control system 10, untwisting system 8, cable arrangement device 9. The tray transmission motor 2 is transmitted to the large 8m tray through the bevel gear and the spur gear on the twisted turntable 1, and then the tray is rotated through the mechanical slewing bearing 5. The tray frequency conversion motor 4 is controlled by the conductive device 6 according to the signal of the linkage main PLC control system 10 or the single-action strand PLC control system 7, and the theoretical setting is obtained, and the tray rotation is realized by the electric slewing bearing 5. In the production process...

Abstract

The invention discloses a three-dimensional stranding, untwisting and cabling machine for a large-length great-section high-voltage photoelectric composite submarine cable, which comprises a stranding rotating plate and a mechanical untwisting device of a supporting plate on the stranding rotating plate, the rotation of the stranding rotating plate is transmitted to the supporting plate through gears, and the supporting plate rotates by means of a mechanical swing bearing. The cabling machine also comprises a variable frequency motor, a PLC (Programmable Logic Controller) control system and an electrical untwisting device of an untwisting system, wherein the PLC control system controls the variable frequency motor to drive the supporting plate to rotate, the untwisting system is arranged above the supporting plate and detects the cable, the detection data is fed back to the PLC control system, the PLC control system compares the detection data with the set untwisting rate, the actual untwisting rate is obtained through comparison, and the deviation value is calculation so as to perform closed loop regulation to the variable frequency motor. The sufficient untwisting of each supporting plate untwisting device before cabling is realized through mechanical untwisting and electrical untwisting.
